Please disconnect your speaker from amp first-if fault goen connect your speaker one by one until you find the bad one-check the cable first and change it with new one and then change the speaker-if the fault still you will have a problem in your amp itself.

1999 Ford Explorer,Door ajar light & Chime goes on & off while driving,int lights & auto headlights won't shut off after car off & all doors closed.


Your best bet would be to find a Tech like this guy , with the right diagnostic equiment . Door Locks Go Crazy 1 Unless you know how to do automotive electrical testing . Your door ajar switch is a input to a body control module . or GEM as ford calls thiers .
Door Locks Go Crazy 2 Your auto lights are controlled pretty much the same .
Electric Testing Techniques You Need to Know

Do you know what DTC"S are ? diagnostic trouble codes ! You probably have a door ajar switch problem . You need a factory or professional type scan tool to check these codes
B1322 Door Ajar Driver Circuit Short to Ground GEM/CTM REFER to Section 417-02 . B1323 Door Ajar Lamp Circuit Failure GEM/CTM REFER to Section 413-01 . B1325 Door Ajar Lamp Circuit Short to Battery GEM/CTM REFER to Section 413-01 . B1330 Door Ajar RF Circuit Short to Ground GEM/CTM REFER to Section 417-02 . B1334 Decklid Ajar Rear Door Circuit Short to Ground GEM/CTM REFER to Section 417-02 . B1338 RR Door Ajar Circuit Short to Ground GEM/CTM REFER to Section 417-02 . B1340 Chime Input Request Circuit Short to Ground GEM/CTM GO to Pinpoint Test C .
  • The Autolamps Are On Continuously
  • Circuitry.
  • Headlamp relay.
  • Light sensor amplifier.
  • Go To Pinpoint Test H .
  • The Autolamp Time Delay Is Inoperative
  • Fuse(s).
  • Light sensor amplifier.
  • Headlamp switch.
  • Circuitry.
  • VERIFY parking lamp operation. If OK, REPLACE the light sensor amplifier. If any parking lamp concerns exist, Parking, Rear and License Lamps REFER to Parking, Rear or License Lamps.

Do you see how complex these systems can be for someone that doesn't deal with these problems on a daily base's ! Check for codes an if there are any , doing the diagnostic's associated with it . Without doing the diagnostic's you could replace parts all day long an not fix the problem .

Gemsound pa 1005 exa keeps shutting off


I Think that something like a transistor is getting hot and then shutting down. Exploring inside might solve the problem of what's getting really hot. You could even get some Servisol Freeze Spray, and wait for it to go off then spray it on the suspected part. That will cool it down and it should start up again. If it does come on, that part will have to be replaced.

WHY MY AMP STILL CLIPPING EVEN IF I KEEP IT IN A


Pleae check to see if you have over loaded the output with a wrong impedance . If so try to test the speakers and connect accordingly.
Next please check if the input source is bringing in poor signals with noise. try to cut off the hig and low freq to set the treble and bass in mid position. next use a ggood ground to take off any transcient voltage on the body due to any leakage in the power circuits. next you can disconnect and opne the panel and check for dry connections, loose connectors or poor filtering in signal processing or power circuits. If you notice any hum check this out. I hope this helps. Good day

Hi...
If it's a straight-up power switch then it will need to be replaced if it works off a relay then the relay is gone.

Gem Sound clipping problem


First of all the EXA-3940 is rated at 350watts per channel in to 8 ohms. The 1400 watts is bridged into a 4 ohm load. Second, the speakers can handle 1000Wats peak with an average of 600 continuous (i'm guessing). That tells me that the amp is underpowered for the speakers. The sensitivity of the amp is such that the mixer is overdriving the input stage. That is what is causing the clipping. If you are looking for more volume, you are probably better off purchasing another amp and running them in bridge mode, 1 per speaker cab. Be careful though, not to overdrive the speaker cabinets either.
